Last year, Microsoft shared some details about their plans for SHA-1 Deprecation Update for blocking SHA-1 signed TLS certificates. Today they shared more details about the plan. Both Microsoft Edge and Internet Explorer will block SHA-1 signed TLS certificates from February 2017. Also, from Windows 10 Anniversary Update, Microsoft Edge and Internet Explorer will no longer consider websites protected with a SHA-1 certificate as secure and will remove the address bar lock icon for these sites. Even though these sites will continue to work, they will marked non-secure for users.
